Any parallel ATA hard drive on the market right now should work for you. I've got 4 of them in my G4. I recommend Seagate because of their 5 year warranty.

Not just any dvd drive will work as a boot drive. Stick to something that is Apple specific. Try Other World Computing. They have many options.

I have used Sonnet products in the past. They are top notch. I currently have a Giga-Designs upgrade in my G4. It has been trouble free for over a year. I have never used Powerlogix, so I cannot speak on their reliability.
